Abstract

The invention discloses degradable environmental-friendly plastic which comprises the following raw materials: polylactic resin, modified poly-beta-hydroxybutyric acid PHB, dinonyl phthalate DINP, pentaerythritol rosin ester, mung bean protein, oxidized cassava starch, alkali hargil, calcium carbonate, musa textilis fiber, linear low density polyethylene-graft-maleic anhydride, gamma-glycidoxy propyl trimethoxy silane, a methyl methacrylate-butadiene-styrol copolymer, aluminum potassium sulfate, citrate, an ethylene-vinyl acetate copolymer, ethylene bis-oleamide, diphenyl-methane-diisocyanate, an anti-mold antibacterial agent, a degradation agent, an antioxidant, a stabilizing agent, a flame retardant, a smoke inhibitor, a tackifier, a softening agent and an ultraviolet light absorber. The degradable environmental-friendly plastic disclosed by the invention is relatively good in tensile strength and elongation at break, good in impact resistance, relatively low in water absorption, good in light transparency, and free of damage to the environment as the plastic can be completely degraded into carbon dioxide and water after 136-141 days.

Description

【Technical field】 [0001] The invention belongs to the fields of plastic preparation technology and environmental protection, and in particular relates to a degradable environmentally friendly plastic. 【Background technique】 [0002] Plastics are widely used, such as plastic toys, plastic bottles, plastic packaging, plastic bags, etc. We cannot live without plastics. Studies have found that plastic products produced from polylactic acid resin can be completely degraded into carbon dioxide and water in a composting environment. Moreover, polylactic acid resin has good compatibility, transparency, solvent resistance and biaxial stretching properties, etc., and can be processed in a variety of ways. At present, the more common plastic products at home and abroad are disposable cups, knives and forks, plates, Plastic bags, non-woven fabrics, etc., theoretically as long as they are plastic products, can be made of this bioplastic material. [0003] However, as we all know, ordin...
